NASA's Lunar Trailblazer Is Officially Lost in Space -- but Maybe Not Forever

NASA's Lunar Trailblazer mission is in jeopardy. It launched on Feb. 27 to send a probe to the moon in search of water. But less than a week after launch, NASA lost track of the spacecraft, which may compromise the mission if NASA can't reestablish contact.
The Lunar Trailblazer mission is part of NASA's SIMPLEx program, which funds low-cost, high-reward missions using smaller spacecraft. These low-cost probes are often included in the launch of larger missions, much like a carpool -- this one launched along with a SpaceX Falcon 9 launch from Florida.

Communications in space are a little more complex than they are here on Earth, but the general principles are the same. In short, a transmitter from the object in space sends data that is captured by a receiver on Earth and vice versa. However, performing these actions requires power, and things can get dicey when the power goes out. That's pretty much what happened with the Lunar Trailblazer.
NASA reports that telemetry from the Lunar Trailblazer showed that it had begun a slow spin. This spin, NASA believes, caused the solar panels to orient themselves away from the sun, causing the satellite to revert to a low-power state.
"The Lunar Trailblazer team has been working around the clock to re-establish communications with the spacecraft," said Nicky Fox, the associate administrator of the NASA Science Mission Directorate. "NASA sends up high-risk, high-reward missions like Lunar Trailblazer to do incredible science at a lower cost, and the team truly encapsulates the NASA innovative spirit -- if anyone can bring Lunar Trailblazer back, it is them."
For now, NASA says the best chance it has at salvaging the Lunar Trailblazer is for it to continue spinning until it reorients itself so that the solar panels get more juice from the sun. It is also working with NASA's Deep Space Network and ground-based observatories to gather data on the lost satellite.
The Lunar Trailblazer's mission is to spend six months floating to the moon, where it'll take high-resolution photos of the entire surface. The purpose of this excursion is to find water
Should NASA reestablish the connection, the mission can still be saved. The connection was lost before the Lunar Traiblazer could perform the various small thruster operations necessary to reach its proper orbit to take off from Earth and fly to the moon. However, the longer the satellite remains unreachable, the more difficult it will be to complete the objective.
"The team is now working to define alternative TCM (trajectory correction maneuvers) strategies that could be used after reacquiring communications and establishing normal spacecraft functionality," NASA said in a blog post. "These alternative TCM strategies may be able to place Lunar Trailblazer in lunar orbit and allow it to complete some of its science objectives."
The Lunar Trailblazer's mission is meant to be a low-cost, high-reward endeavor to photograph any water on the moon's surface to better ascertain how much is there and what forms it takes. Should NASA reconnect with it and the new TCM strategies are successful, the satellite will still take about six months to reach our nearest celestial neighbor to begin taking measurements.
Connection issues with objects in space are nothing new for NASA or any other space agency. Late last year, NASA had to activate a radio that Voyager 1 hadn't used in 40 years to reestablish contact with the ancient satellite. During a NASA-hosted livestream on Twitch, connection to the International Space Station was lost while astronaut Don Pettit was in mid-sentence.
Sometimes, connection losses are expected. For example, the Blue Ghost mission stuck its moon landing earlier this week, and that mission will end once the equipment loses its solar power and the connection is lost. In short, connection issues are an annoying but not infrequent issue with space objects.

Dog's ashes among dozens to rocket into orbit this weekend

Bone voyage! A beloved dog named Franz will take his final leap this weekend — into Earth's orbit. The yellow labrador's ashes will be on board the inaugural Perseverance Flight from Texas-based Celestis Inc., which is scheduled to launch around 5:30 p.m. Sunday from Vandenberg Space Force Base in Santa Barbara, CA. 4 Franz was like a sibling to Elizabeth Moore before he died at age 13 in October 2020. Celestis, Inc Carrying a total of 166 titanium and aluminum capsules, each about a quarter to a half-inch in size and filled with DNA or cremated remains, the 23-foot-tall SpaceX Falcon 9 rocket will take two trips around Earth's low orbit at a mind-boggling 17,000 mph. The space flight will last about three hours before the rocket — still carrying its priceless payload — re-enters the atmosphere and lands in the Pacific Ocean somewhere between Alaska and Hawaii, according to Celestis CEO and co-founder Charles Chafer. A recovery ship, which was already out at sea Friday in anticipation of the launch, 'will track the incoming rocket, hopefully get a visual on it, and then go pick it up out of the ocean,' Chafer explained. 4 The Texas-based company Celestis Inc.'s inaugural Perseverance Flight will take two trips around Earth's Lower Orbit after blastoff on Sunday. The capsules will first be transported to Germany, then, within two months, distributed back to the families, who each paid a whopping $3,500 to send their loved one to the stars. While the price to send Franz on the voyage was 'a lot more' than the pooch itself, his owner, Harvin Moore, said with a laugh, it was only fitting for the 'space-fanatic' Moore family to send the pup beyond the stratosphere. 'He was the best dog, just so soft and nice and loved hugs,' recalled Moore, 60, who lives in Dripping Springs, Texas, just outside Austin. 4 The Moore family can't wait to watch their beloved pooch go galactic. Celestis, Inc Franz, who was 13 when he died in October 2020, was more like a sibling than a pet to Moore's now 26-year-old daughter, Elizabeth, and son, Quinn, 21, he said. Now, the family can't wait to watch the good boy go galactic. 'The emotional power of being with a group of people who are celebrating the life of a loved one in this way … it's amazing. It's nothing we'll ever forget,' said Moore. 'It's just pure joy.' 4 The Perseverance Flight will carry a total of 166 titanium and aluminum capsules, ranging in size from a quarter to a half-inch, filled with DNA or cremated remains. Celestis, Inc 'Many people whose ashes and DNA are flying are people that always wanted to go to space in their lifetime but were never able to do that. It also helps families move from feelings of grief to joy,' Chafer said. The cremated remains of Wesley Dreyer — an aerospace engineer who helped investigate the cause of the Space Shuttle Challenger's shocking explosion after takeoff on Jan. 28, 1986 — will also be on board the Perseverance Flight, as well as DNA from a living, 3-year-old German boy.

Regional students participate in University of Idaho's coding and robotics camp

Jun. 21—MOSCOW — It may not be a summer camp in the traditional sense, but the University of Idaho's summer Robotics Coding Camp is helping local students learn skills that can help them in the future. Regional middle and high school students spent a week on the Moscow campus learning about computer programming and engineering. The students typed and clicked away at their computers mastering skills many people don't learn until they are older. Erin Lanigan, UI assistant director of student engagement and STEM outreach, said one of the goals for the program is to help prepare students for entering the workforce where computer science and engineering skills are among the top needs. At this age, they are beginning to decide what they want to do when they grow up. "They have to see it to know they can be it," she said. Moscow Middle School student Corinne Bowersox, 12, already has a job in mind. "I'm actually interested in being a NASA engineer," she said. During this week's camp, she used coding to create her own video game where the goal is to catch fortune cookies and eggs before they hit the floor. She also learned how to control a small robot on wheels. She said coding is an easy way to learn a new hobby and people can share their work with other creators.
